User Password
When a User Password is set, the computer cannot be used until a valid password
is typed from the keyboard.
Administrator Password
When an Administrator Password is set, it deters unauthorized persons from
changing configuration settings. If you are responsible for maintaining the settings
of several computers, you might want to set an Administrator Password.
After you set an Administrator Password, a password prompt is displayed each
time you try to access the Setup Utility program.
If both the user and administrator passwords are set, you can type either
password. However, to change any configuration settings, you must use your
administrator password.
